Kii Sakai Kō Lighthouse

Fl Green 3s🇯🇵Minabe, JPOperational

Located at the end of the south breakwater of Sakai fishing port, this 8-meter white concrete post structure guides vessels into the harbor near Haya. Built in 1984, it stands on a square, 1-story concrete equipment room. The light emits a single green flash every 3 seconds from a focal height of 12 meters, with a geographic range of 11 nautical miles. The site is accessible to the public, though the tower itself remains closed. This concrete post and building mark the entrance to the port, which is situated northwest of Tanabe.

Why it matters: The Kii Sakai Kō lighthouse is important for demarcating the south breakwater, providing a safe channel into Sakai fishing port and helping to prevent collisions with harbor infrastructure.
